Terrae Dragons are primarily herbivores who prefer to eat from the tops of trees. However, due to their massive size, they must rely on small, specialized scales to absorb and convert energy from the sun. Since they live in tightly-knit groups, this form of energy absorption helps preserve the forests in which these dragons reside.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

"Unter der Eiche" means "underneath the oak", which is where the other Terrae Dragons found him as a hatchling, nibbling on some leaves all by himself. He was nearly grown up but hadn't found a home yet, but that was soon remedied when he was accepted into their group. He is a very calm, peaceful dragon, slightly smaller than average male Terrae Dragons but strong enough to fly even in the stormiest weather, if he feels like eating the leaves from the top of a tall tree.
